WINDOW SASH HOLDER Filed June 7, 1954 2,829,911 WINDOW SASH HOLDER Frank L. Green,

facturing Illinois Rockton, Ill., assignor to Green Manu- Company, Rockton, 111., a corporation of This invention relates to a window sash holder of the type in which a cup-shaped body member slidable in a bore in a window sash is urged outwardly and into frictional gripping engagement with the window jamb by yieldable means such as a spring disposed within the cup and acting between the bottom thereof and a disk retained within the cup. A screw having limited axial movement relative to the disk is threaded into a nut adapted to grip the sash at the bottom of the bore and extends through a counterbore in the sash for access from the inner side of the latter.

One object of the invention is to construct a sash holder of the above character in a novel manner to facilitate assembly of the parts, to simplify the construction thereof, and to avoid faulty operation of the holder caused by cocking of the cup in the bore.

Another object is to hold the screw and disk assembled by novel detachable connection which facilitates formation of a rounded edge at the open end of the cup by enabling the screw to be assembled to the disk after the edge is formed.

A more detailed object is to form the disk with an opening or slot having an enlarged portion offset from the center of the disk and permitting endwise insertion of the screw when the latter is spaced from the disk axis and a narrow portion at the center of the disk smaller than opposed abutments on the screw but large enough to receive a reduced section of the screw between the abutments when the screw is shifted laterally into coincidence with the axis.

Other objects and advantages of the invention will become apparent from the following detailed description taken in connection with the accompanying drawings, in which Figure 1 is a sectional view of a window sash and a holder therefor embodying the novel features of the present invention.

Fig. 2 is a perspective view of the holder.

Fig. 3 is a sectional view of the holder taken along the line 3-3 of Fig. l. 2

Fig. 4 is a view similar to Fig. 3 with the holder parts in different positions.

Fig. 5 is a view similar to Fig. 3 with one holder part removed.

Fig. 6 is a plan view of the holder with some of the bore 11 in the sash 12 and is yieldably urged by a spring 13 outwardly away from the latter for frictional gripping engagement of its bottom wall 14 with the window jamb disposed within the cup and acts of the cup and an annular disk or plate 16 which is reciprocable axially within the cup and is connected to the inner end of a screw 17. The latter extends axially of the cup and through a counterbore 18 in the sash with its slotted outer end 19 exposed as shown hired States Patent three in Fig. 1. A nut 20 threaded onto the shank of the screw is formed with prongs 21 which bite into the sash at the bottom of the bore 11 to prevent turning of the nut so that, as the screw is turned and moves inwardly relative to the nut and the sash, the disk is shifted axially to compress the spring and increase the force urging thecup against the jamb.

The open end of the cup 10 is shaped to hold the disk 16 and the spring 13 assembled within the cup while avoiding faulty operation of the holder due to digging of the cup end into the bore wall 11 upon cocking of the cup relative to the bore. To these ends, the edge 22 of the open end of the cup is rounded or bent inwardly around its periphery to form an inturned flange or continuous internal shoulder whose inner periphery is smaller in diameter than the disk 16 to limit outward movement of the disk under the action of the spring.

press (not shown) after first the spring and then the disk have been inserted into the cup, the freely expanded length of the spring being less than the length of the cup so that no axial pressure is required to hold the disk in the cup before the cup edge is bent inwardly.

The present invention contemplates a novel construction of the screw 17 and the disk 16 to enable these parts to be connected together after the disk and the spring 13 are assembled in the cup 1 0 so as to leave the open end of the latter and the outer side of the disk exposed and unobstructed and thereby facilitate formation of the flange 22 to retain the disk in the'cup. For this purpose, the disk is formed with a hole or slot 24 therein whose defining edge forms oppositely facing abutments and cup axis. Also, formed with opposed axially spaced abutments adapted during such lateral shifting to straddle the defining edge of the hole and thereafter engage such edge to limit axial movement between the screw and the disk.

In the present instance, the opposed abutments on the the latter diameters being approximately equal.

The hole 24 in the disk 16 herein comprises an enlarged circular portion 26 offset from the center of the disk and having a slightly larger diameter than that of the head 23 to receive the latter when the screw is offset from the disk center and shifted axially and inwardly. The enlarged hole portion 26 opens into a smaller circular portion 27 concentric with the disk axis and smaller in diameter than the head and the screw shank but large enough to receive the neck portion 25 when In assembling the screw 17 and the disk 16 after the nut 20 has been threaded onto the screw and the edge 22 of the cup 10 has been bent inwardly to hold the disk 16 and the spring 13 in the cup, the screw is grasped by itsthreaded portion and the head 23 is inserted into the enlarged part 26 of the disk hole 24 (see Fig, 4) and moved inwardly past the disk. Then, the screw with the nut thereon is shifted bodily and inwardly in a radial direction to move the neck 25 into the narrow portion 27 of the hole to aline the screw axially with the disk and the cup (see Fig. 3). In this position of the screw, its movement axially of the disk is limited in the outward direction by abutment of the head with the defining edge of the small hole part 27 on the disk as shown in Fig. 6 and in the inward direction by abutment of the screw shank with the disk as shown in Fig. 1. To hold the screw and the disk assembled before the holder is inserted into the sash bore 11, the nut 20 is turned and tightened against the open end of the cup as shown in Fig. 6. With the disk and cup thus clamped together, the screw is held frictionally against lateral movement outwardly along the slot 24. In the final installation on a window, the wall 11 of the sash recess maintains the desired axial alinernent of the screw and the disk.

It will be apparent that, due to the rounding of the edge 22 of the cup 10 at its open end, sharp edges are eliminated and the cup may slide freely in the sash bore 11 even though cocked out of axial alinement with the bore. Such bending in of this edge around its entire periphery can be achieved easily in a pressing machine operation because, with the screw 17 still separated from the disk, the open end of the cup is free of obstruction to receive the pressing tools. By virtue of the novel disengageable connection between the screw and the disk, these parts may remain separated until after the flange bending operation and then may be secured together in their finally assembled relation by simple hand operations.
